返回 Doctrine_collection null
我有一个非常简单的问题。我到处找，但什么也没找到。
我有一个这样的 Doctrine 查询：
return Doctrine_Core::getTable('something')->createQuery()->where('where clause')-
>execute();
我想检查它是否返回某些内容。就这样。如果它的内容为空，我不会做其他事情。空不起作用，isset不起作用，count不起作用。我该怎么办？
我知道这很简单，但我不知道该怎么做。
任何建议将不胜感激。
i have a very simple question. i searched for it everywhere but i didn't find anything.
i have a Doctrine query like this:
return Doctrine_Core::getTable('something')->createQuery()->where('where clause')-
>execute();
i want to check whether it returns something or not. just it. if it's content is null i don't do other stuff. empty doesn't work, isset doesn't work ,count doesn't work . what am i suppose to do?
i know it's so simple but i don't know how to do it.
any suggestions would be appreciated.

对结果数组执行
->count()怎么样？http://groups.google.com/group/doctrine-user/browse_thread/thread/b0fe08b9b3da3e41/22e036fe4674f619?pli=1
What about executing
->count()on result array?http://groups.google.com/group/doctrine-user/browse_thread/thread/b0fe08b9b3da3e41/22e036fe4674f619?pli=1
$obj = Doctrine_Core::getTable('something')->createQuery()->where('where 子句')->execute();
如果（$obj == null）
{
}
在此处输入代码else
{
}
$obj = Doctrine_Core::getTable('something')->createQuery()->where('where clause')->execute();
if ($obj == null)
{
}
enter code hereelse
{
}
